Everything that increases the cost of doing _anything_ is a "tax on the poor"; that's just a particularly emotional way of describing exactly what it is that poor people don't have (money/power). In a city like London there is actually no reason to drive around a diesel car in the centre. It's done for convenience only. Non-diesel vehicles exist, electric vehicles exist, very soon there'll be enough to fill the roads (Central London is really quite small), done. I don't think it should be banned - I think a tax is far more appropriate (that's actually what we're doing) - but ultimately, yes, poor people will be hit harder. We don't allow burning rubbish to heat homes either. That's a "poor tax" too.
